[0038] From the above, it can be seen that compared with the prior art, the drilling machine described in this embodiment has the following advantages: ① The jig device can firmly fix the workpiece thereon in a vertical manner, so that the drill module in the drilling device can easily perform drilling processing on the side of the workpiece, with high drilling efficiency and high drilling quality. ② The drilling machine is equipped with a plurality of jigs and a plurality of drill modules, which can realize drilling processing on multiple workpieces at one time, greatly improving production efficiency and meeting production needs well. ③ The drill module collects waste materials (such as waste chips generated during drilling) in a negative pressure manner, which not only effectively improves the processing environment, but also saves the cutting fluid conventionally used in the prior art (that is, saves consumables), and saves manpower for cleaning the cutting fluid. In short, it greatly saves production costs.

[0039] The specific structure of the drilling machine described in this embodiment is described in detail below.

[0040] First, please refer to the attached Figure 1 To the attached Figure 5 As shown, the preferred implementation structure of the jig device 1 of this embodiment is as follows: the mounting member 10 is provided with a slide 100, a mounting frame 101 vertically and fixedly mounted on the upper side of the slide 100, and a plurality of partitions 102 spaced along the second horizontal direction on a vertical side (such as the "front vertical side") of the mounting frame 101. The plurality of partitions 102 further divide the vertical side of the mounting frame 101 into a plurality of mounting sections 1010. The plurality of jigs 11 are mounted on the plurality of mounting sections 1010 in a one-to-one correspondence, and each jig 11 cooperates with its corresponding partition 102 to receive and secure a vertically placed workpiece. That is, in this embodiment, the jig 11 cooperates with the mounting member 10 to secure the workpiece vertically to the jig 11.

[0041] Regarding the separator 102, the preferred implementation structure of this embodiment is: Figure 4 As shown, the separator 102 includes at least two dividing blocks 1020 arranged in parallel along the vertical direction on a vertical side of the mounting frame 101. As can be understood, the dividing blocks 1020 can not only enable the separator 102 to have the functions of dividing and stopping / positioning the workpiece, but also have a simple structure, easy assembly, and low production cost.

[0042] Furthermore, in this embodiment, a magnetic block is embedded in the dividing block 1020, so that the dividing block 1020 / the separator 102 also has the magnetic attraction and positioning function for the workpiece, further improving the limiting and fixing effect on the workpiece.

[0043] In addition, in this embodiment, the number of the partition blocks 1020 in different partitions 102 is the same or different. Figure 3 and attached Figure 4 As shown, if the first horizontal direction is defined as the front-to-back direction and the second horizontal direction is defined as the left-to-right direction, the two leftmost and rightmost separators 102 are each provided with two dividing blocks 1020, while the other separators 102 located in the middle are each provided with three dividing blocks 1020. Of course, this embodiment does not impose any restrictions on the number, shape, and size of the dividing blocks 1020, and the specific size is determined according to processing requirements.

[0045] Furthermore, the fixture body 110 is provided with a receiving vertical surface 1100 for the workpiece to rest against; the positioning assembly includes a first positioning member 111, a second positioning member 112 and a third positioning member 113, each of which is provided in plurality, wherein the plurality of the first positioning members 111 are spaced apart on the bottom side of the receiving vertical surface 1100 to support the workpiece; the plurality of the second positioning members 112 and the plurality of the third positioning members 113 are spaced apart on the receiving vertical surface 1100, respectively, and the second positioning member 112 can be plugged in to position the workpiece (understandably, the second positioning member 112 is used to plug and cooperate with the hole on the workpiece), and the third positioning member 113 can be adsorbed and positioned.

[0046] It can be understood that the positioning component provides the workpiece with an upward supporting force (specifically provided by the first positioning member 111), an adsorption force (specifically provided by the third positioning member 113) and an insertion limiting effect (specifically provided by the second positioning member 112), and the workpiece is combined with the stop limiting effect and magnetic attraction force in the left and right directions provided by the separator 102 to the workpiece, so that the workpiece can be firmly and stably fixed on the fixture body 110.

[0047] Furthermore, the fixture body 110 is a plate-shaped structure, and one side elevation of the fixture body 110 along the first horizontal direction is the receiving elevation 1100; it is understandable that the attachment Figure 1 It can be seen that the front elevation of the fixture body 110 is the receiving elevation 1100 .

Based on the aforementioned arrangement of the mounting sections 1010, this embodiment further includes abutment blocks 103 positioned below each mounting section 1010 for abutting the jig 11 to provide support and restraint. Furthermore, a sensor 12 for sensing a workpiece is positioned adjacent to each mounting section 1010 for detection and error prevention.

[0050] It is understandable that when the mounting section 1010 is flush with one side (such as the "front side") of the slide 100 along the first horizontal direction, the abutment block 103 can be fixedly connected to the lower side of the slide 100 (see attached FIG. Figure 3 and attached Figure 4 and when the mounting section 1010 extends out of one side of the skateboard 100 along the first horizontal direction, the abutment block 103 may be fixedly connected to the lower side of the mounting section 1010.

It can be understood that, ① in this embodiment, the plurality of drill modules 20 are first installed on the hanging plate 5 according to the layout and spacing of the plurality of jigs 11, and then the hanging plate 5 is driven to move along the second horizontal direction, so that the plurality of drill modules 20 can be moved one by one to above the plurality of jigs 11. ② In the drill module 20, the drive mechanism B can drive the mounting base 200, the motor 201, the drill bit 202 and the slag suction pipe 203 to move up and down together, and the motor 201 can drive the drill bit 202 to rotate, that is, the drive mechanism B and the motor 201 cooperate to drive the drill bit 202 to drill the workpiece. The slag suction pipe 203 uses negative pressure to suck away the waste chips generated during the drilling process, which well ensures the cleanliness of the processing environment.

[0054] Furthermore, the specific structure of this embodiment to achieve that the hanging plate 5 can be slidably arranged on the beam 4 along the second horizontal direction is: Please continue to refer to the attached Figure 1As shown, a slide rail B40 extending along the second horizontal direction is fixedly provided on the crossbeam 4, and the hanging plate 5 is slidably connected to the slide rail B40.
